radiation and phase change for multilayer composite insulation structure is built in this paper
radiative heat transfer in semitransparent participating material of the composite insulation structure is simulated by Monte Carlo method (MCM)
and then be regarded as radiative source term of the energy equation
while energy equation is solved by finite volume method (FVM). Transient heat transfer characteristics of three different typical composite insulation structures
which are respectively composed of fiber blanket insulation and metal film
fiber blanket insulation
fiber reinforced aerogel and metal film
fiber blanket insulation
fiber reinforced aerogel
phase change insulation materials and metal film composite insulation structure
are analyzed and compared. Computational results show that the structures and components of the composite insulation significantly influence its transient heat transfer characteristics. The proposed research work can provide guidance for optimization design of the composite insulation structure.
